The east coast of Chi Ming is the coastline of stone railings, while the three directions of south, west and north are the curved banks of traditional gardens. The whole structure of these curved banks is divided into two parts. The part near the bottom of the pool is a strip-shaped stone foundation with a thickness of about 90 cm, and the structure is about 100 cm from the ground, which is formed by the superposition of sea reefs. These reefs were collected from Zhoushan Archipelago, and the price in those days was 40 yuan per ton, which was 45 yuan per ton with freight 5 yuan.
After the water disappears, as long as you look closely, you will find that although the structure of the bank is the same, the state of the north bank and the south bank seems to be very different. The shape of the strip stone foundation on the north shore is almost the same as the structure and vertical direction of the Shanghai reef. However, the structural strike of the strip stone foundation on the south bank is completely different from that of the upper reef.
This confirms an anecdote about Chi Ming circulating in the museum.
In those days, the scope of digging the pool was roughly east of Bashi Pavilion and west of the south extension axis of Baie Pavilion. This area used to be a wasteland, but later it was slightly tidied up, with iron cows, crouching tigers and some stone statues that have disappeared. The earliest stone dike foundation in Mingchi and the curved reef dike on it were all completed by Tianyi Pavilion's own workers, but it is said that Mr. Chen Congzhou was furious after reading it:
"Are you building a bunker? ! "
Everyone asked Mr. Chen how to remedy it, so the scene suggested by the teacher to Mr. Ruan reappeared when the Shanghai Yuyuan Garden was restored.
"This rockery, still want to change ..."
It's just that the location is not in Yuyuan East Garden, but in Tianyige East Garden.
So, Mr. Chen invited Master Zhang from Changshu, who participated in the maintenance of the rockery in Yuyuan Garden (unfortunately, we don't know his full name yet), and combined with the rockery on the south bank, all the coastlines were rebuilt. Therefore, although the strip stone foundation under the shoreline measured from the south of Mingchi is still a semicircle similar to the north shore (the "bunker" as Chen Congzhou said), the curved shore of the upper reef has completely retreated, making a more complex and rich linear shape, and even the scale of some nozzles has changed.
Today, it seems that the foundation of the south bank is not as neat as that of the north bank, but it has laid the basic pattern of "winding along the river and rippling in Shui Yang". This slightly messy foundation hidden under the waterline is also a witness to the optimization and adjustment that year.
Since last week, the silt at the bottom of the pool has been cleared, and the bottom of the pool is directly exposed. Let's see the structure at the bottom clearly.
First of all, there are pine stakes in a group several meters from west to east, and each group of pine stakes consists of about nine stakes, which is similar to the shape of a nine-square lattice. My initial judgment was to fix the coastline, but the positions of several groups of pine stakes almost crossed the open pool. Is it necessary to repair the bottom of the pool? So I asked my predecessors who had participated in the transformation of Dongyuan in those years, and even dug up a past event.
At that time, Tianyi Pavilion tried to "copy" the zigzag bridge of Shanghai Yuyuan Garden into the East Garden ... so it began to build the foot of the bridge across Mingchi. It was Mr. Chen Congzhou who stopped the next work in time, on the grounds that the pool was too small and it was not nice to go straight to the curved bridge. In fact, there is another reason for my judgment-the original intention of digging the pool.
In Chen Congzhou's original plan, there was no swimming pool in the East Garden. It was not until Tianyi Pavilion moved from north to south on the extension line on the south side of White Goose Pavilion that two huge buildings (now Ninghui Hall and Linquan Cliff Hall) were built, and Mr. Chen discovered that the two buildings in Dongyuan were really too big! The remedy is to dig a pool in the open space on the west side of the two buildings. Once the swimming pool appears, visitors to the park will either look at the water features close to the building, and then they will ignore the size of the building; Or go to the building opposite the pool, and the building won't be so big after pulling away.
So the bridge water completely broke Mr. Chen's delicate layout, and it's strange that he is not angry!
As the saying goes, the article is eternal, and the gains and losses are well known. Isn't it? !
At the bottom of the exposed open pool, we found two square wells near the bottom of the East pool. Many friends from the museum came to ask, Digging a well under the pool, let's have feng shui. ...
Hehe, it really has nothing to do with Feng Shui. In fact, there are still many ways to drill wells below the water surface in Ningbo. There are also wells under the Moon Lake.
The function of these wells under water is traditionally called "sitting water" or "gathering water". Before the Jin Dynasty, Ningbo was a shallow sea. There is an impermeable sea Xiangtu four to six meters underground, which is traditionally called "blue mud". Below the silt is a permeable layer. Digging wells at the bottom of artificial waters can create a lowest place above the blue mud, where the groundwater above the blue mud can gather; On the other hand, wells that have penetrated blue mud can also suck groundwater deeper (permeable layer).
In Xu Shu's West Lake in the Song Dynasty, it was mentioned: "In the middle of Ningnian, there was a drought at the age of twenty. He closed the border and took it from it (Moon Lake). The lake dried up and it was another well, so he set up a house to guard it. " Translated, that is to say, around 1070, there was a drought in Ningbo, and the people of the city lived by drinking Moon Lake. Moon Lake was drunk, and they continued to drill a well at the bottom of the lake to get water. Security guards were specially sent to the mountain next to the well ... This well obviously drilled through the impermeable layer to continue to supply water.
The exploration of the East Garden may continue. In the process of our construction and maintenance, it is possible to open a door of time at any time, in which we can see the traces of countless predecessors' work. Today, as a new generation of defenders, we should not only complete the current task, but also protect the traces of the past. We should also faithfully record what we see, so that future successors can clearly see how the baton is passed. A person's life is short, but if he can participate in a bigger and longer chain, the so-called meaning will come into being.
I remember a senior said that pine stakes were found in the construction of Nanyuanchi, and I am looking forward to the maintenance of Nanyuan next month. ...
